Abstract (en)
[origin: EP0940240A2] A heat insulating paper cup with improved insulation in areas where printed matter exists. The printed matter is applied using a water-based alkyd or epoxy ink. In one embodiment the cup can include a body member having an inside surface and an outside surface, and a bottom panel member having a upper surface and a bottom surface. The body member is coated on its outside surface with a foamed synthetic resin, and on its inside surface with an unfoamed synthetic resin. The bottom panel member is optionally coated on its upper surface with a foamed or an unfoamed synthetic resin. The body member and bottom panel member are oriented and joined to form a seal at an interface between a portion of inside surface of the body member and a portion of the upper surface of the bottom panel member. The printed matter is applied prior to foaming of the synthetic resin on the outer surface of the cup. <IMAGE>
